Sequence valves
Description
Sequence valves are applied as directly-controlled sequence valve in hydraulic clamping systems. The compact design of the sequence valves enables space-saving installation directly into the fixture. Inlet pressure and outlet pressure are always identical at sequence valves. This is what makes this valve type ideal for use in sequence controls. Single-acting cylinders only require one feed line from the pressure generator for operation. The design allows valve combinations which can be flanged with the help of a joint P-connection and standard components to a block.

Valve combinations:
Combinations of sequence valves are mounted with one in-valve (P) and a maximum of four flanged-on sequence valves. Bore holes provide them with hydraulic oil. O-rings function as sealings between the valve housings. Inlet and outlet pressure are always identical for sequence valves. This makes this type of valve ideal for sequence control application.
The drawing symbolizes a clamping fixture the way it can be used in production. Once the pressure is applied the single-acting cylinder [1] is protracted.
Once the opening pressure is acquired the inlet valve [A1] opens and activates the swing clamp [2].
The support element [A2] clamps the support piston once the opening pressure in the sequence valve [A2] is acquired.
Sequence valve [A3] activates the swing clamp [4] to complete the clamping process.
When releasing the device, the hydraulic oil flows back to the pressure generator through the integrated non-return valves.
